Direct-to-consumer advertisements for prescription drugs: whatare Americans being sold? Steven Woloshin, Lisa M Schwartz, Jennifer Tremmel, H Gilbert Welch prescription drug appeared in Reader’s Digest in 1981 billion on direct-to-consumer advertisements for prescription drugs in 1999. Our aim was to establish what advertisements were published, and the US Food and messages are being communicated to the public by these Drugs Administration (FDA) became worried that little was known about the potential effect of suchadvertisements on the public. Consequently, in 1983, Methods We investigated the content of advertisements, the FDA initiated an advertising moratorium while it which appeared in ten magazines in the USA. We examined seven issues of each of these published between July, options.2,3 Although they concluded that “direct to the public prescription advertising was not in thepublic interest,”3 the FDA lifted the moratorium in Findings 67 advertisements appeared a total of 211 times 1985 because of concerns about freedom of speech during our study. Of these, 133 (63%) were for drugs to ameliorate symptoms, 54 (26%) to treat disease, and 23 in place were sufficient to protect the consumer.4 (11%) to prevent illness. In the 67 unique advertisements, promotional techniques used included emotional appeals (45, 67%) and encouragement of consumers to consider medical causes for their experiences (26, 39%).

The codes allowed us to measure several factors: (1) type of product—we categorised theindications for every medication and then grouped these indications into those intended to ameliorate symptoms,to treat disease, and to prevent disease; (2) descriptionof benefit and side-effects—we noted whether the benefit of the product was described with qualitativelanguage (eg, it works) or with quantitative statements (eg, it lowers the chance of dying by 30%). We codedthe presentation of the product’s side-effects in muchthe same way. We also coded four other aspects of the presentation of benefit: what studies were cited to support this benefit, whether the benefit was compared to that of other similar medications, the use of personal Figure 1: Amount spent by pharmaceutical companies on testimonials about benefit, and whether the widespread use of the drug was mentioned (eg, most prescribed *Television, print, and other.

We compared the median number of advertisements per issue across the three types of magazines with Kruskal- Wallis tests. This comparison was two-sided and was judged significant at p<0·05. For all analyses we used STATA version 6.0 (College Station, TX, USA).
During the 1 year study, we identified 211 direct-to- consumer pharmaceutical advertisements in 70 issues of selected magazines (median 2.5 advertisements per 42 000 issue, range 0–12). 59 (84%) issues contained at least 42 000 one advertisement. Advertisements for products designed for symptom relief were most frequent (133,63%). Drugs for symptoms of allergies and those related 57 000 to menopause (eg, hot flashes and vaginal dryness) 49 000 accounted for most of the advertisements in this 55 000 category.

At the same time they encourage The results of our study suggest that direct-to-consumer consumers to believe that a problem might exist (where advertisements are common in popular magazines, they previously would not) and that a pharmacological particularly in those aimed at women. Furthermore, solution is the appropriate way to deal with it.

Logistically, the systematic sampling experience is officially recognised as a symptom of and analysis of such advertisements is easier than with disease, and the affected person is now a patient.

For example, whereas there addition to the difficulties of labelling,33 this process can might be much discussion about which phrase stood out result in harm, by exposure of people to medication in a radio spot, there was no ambiguity about the side-effects and by starting other medical processes in headline for a magazine advertisement, which was motion (ie, testing).
